Study Notes
Dystocia
- Defined as difficult labor indicating complications during childbirth.
Main Components of Labor
- Power: Refers to uterine contractions responsible for moving the fetus through the birth canal.
- Passenger: Represents the fetus.
- Passageway: Indicates the birth canal.
- Psyche: Encompasses the perception and emotional response of the woman and her family regarding labor.
Dysfunctional Labor
- Current terminology for inertia, indicating ineffective labor patterns.
Inertia
- A term describing sluggish uterine contractions resulting in weak labor force.
Common Causes of Dysfunctional Labor
- Inappropriate use of analgesia.
- Pelvic bone contraction narrowing the birth canal, e.g., rickets.
- Poor fetal position, specifically head extension rather than flexion.
- Uterine overdistention from conditions like multiple gestation or hydramnios.
- Cervical rigidity due to full rectum or urinary bladder impeding fetal descent.
- Maternal exhaustion or first-time labor (primigravida status).
Uterine Contractions
- Fundamental mechanism propelling the fetus through the birth canal.
Oxytocin
- Hormone that significantly increases uterine contraction strength and frequency; can initiate labor if necessary.
Hypotonic Contractions
- Occur post-analgesia or due to complications like uterine overstretching or laxity (e.g., grand multiparity).
Contraction Frequency
- During hypotonic contractions, only 2-3 contractions may occur within a 10-minute period.
Hypertonic Contractions
- Characterized by excessive uterine activity; typically 15 mmHg is the resting tone.
- Results from multiple pacemakers stimulating contractions or myometrial fibers failing to relax post-contraction.
Latent Phase
- Stage of labor where hypertonic contractions are most prevalent.
Precipitate Labor
- Defined as very rapid labor, characterized by intense contractions leading to quick delivery.
Facilitators of Precipitate Labor
- Conditions such as grandmultiparity or the induction of labor with oxytocin can increase the likelihood of precipitate labor.
Risks for Fetus in Precipitate Labor
- Potential occurrence of subdural hemorrhage due to rapid delivery.
Risks for Mother in Precipitate Labor
- Possible birth canal lacerations, uterine bleeding, shock, and increased risk of infection.
Causes of Precipitate Labor
- Strong, efficient uterine contractions.
- A smooth birth canal facilitating rapid delivery.
- Previous history of precipitate labor.
- Smaller than average fetal size.
- Labor induction through prostaglandin use or fertility treatments.
Signs and Symptoms of Precipitate Labor
- Sudden onset of closely spaced intense contractions.
- Persistent and painful contractions.
- Urge to bear down, resembling a bowel movement.
- Immediate need to pass stools.
Risks for Babies during Precipitate Labor
- Increased likelihood of infections or aspiration of meconium and amniotic fluid during rapid delivery.
